Quick answer
Estimate cubic yards of topsoil needed for lawns, beds and grading using measured square footage and depth. Use the working RenoMetric calculator below for the actual estimate, then use this page to check assumptions, package rounding and project-specific considerations.

Worked planning example
1,000 ft² covered 2 in deep is about 6.17 yd³ before compaction or grading allowance.
Common uses
- New lawns
- Garden beds
- Low-spot filling
- Landscape grading
How to get a better estimate
Measure the actual project rather than relying on listing dimensions. For irregular spaces, split the surface into simple measurable sections and add the results. Use the exact product label for package coverage, yield, density or square-foot coverage whenever it is available.
Keep waste and package rounding as separate steps. Waste covers cuts, breakage, pattern matching and unavoidable offcuts. Package rounding reflects the fact that many materials are sold only in complete bags, boxes, bundles or cans.
Before you buy: this page is a planning guide, not a contractor quotation or structural design. Verify final quantities with the product manufacturer, supplier or installer when project conditions could materially change the result.
Topsoil Calculator FAQ
How many yards of topsoil cover 1,000 square feet?
Coverage depends entirely on depth. At 2 inches, the geometric volume is about 6.17 cubic yards.
Does topsoil compact?
Yes. Delivered material may settle after spreading, watering and traffic, so a project-specific allowance can be useful.
Should I measure slopes differently?
For modest slopes, surface area may be close to plan area. Steeper sites benefit from more careful section measurements.
